Overview

Randomized trial investigates mechanical, thermal, and rheological properties of PLA/TPU with carbon nanotubes, suggesting innovative material applications.

Key Points

  • This research aims to explore how the mixing sequence and carbon nanotube loading affect the properties of PLA/TPU nanocomposites.
  • PLA/TPU blends with carbon nanotubes were prepared via melt mixing.
  • CNT/polymer masterbatches were used to enhance dispersion.
  • Morphology, mechanical, thermal, and rheological properties of nanocomposites were systematically evaluated.
  • The highest tensile strength and toughness were achieved at 0.5 wt% CNT.
  • SEM micrographs showed TPU droplet morphology decreasing in size with 0.2 wt% CNT addition.
  • Increased PLA crystallinity was observed with TPU blending and additional CNT, while cold crystallization temperature remained unchanged.
